Another advantage of studying the Painted Lady Butterfly is that the eggs are available from Carolina Biologicals. This company has been a source for teaching supplies for decades, and still provides quality biologicals. Most butterflies kits on the market provide only the caterpillars. Carolina provides eggs that allows the students to study the hatching of the caterpillar, an interesting bonus. However, one must be ready to immediately place the eggs with the food supply once they arrive by fast two day shipping, shipping that unfortunately adds extra cost. The other alternative is to spend time on field excursions in hopes of finding the eggs on host plants.
